Watch Lourdes Leon get wet and wild on the beach.

Madonna‘s 20-year-old daughter, Lourdes Leon, was baring it all in Miami on April 10 — and wasn’t bothered to show off her hairy pits in the process! She spent the day with friends on the sand as they frolicked in-and-out of the water occasionally.

“Lourdes hates seeing how stressed her mom’s been throughout this whole custody ordeal. She thinks Rocco is a brat who needs to pull himself together and stop playing his parents off against each other,” an insider told RadarOnline.com in October.

Previous reports revealed that the custody battle was finally settled last year in September after an 8-month-long debate with ex Guy Ritchie, who had been allowing Rocco to live in London with him. The court ruled to continue letting Rocco stay with his dad.
